Your wildest dreams (See also: Nightmares) have been answered! Capcom and Namco Bandai have confirmed that Pac-Man and Mega Man will
exclusively appear in the PlayStation Vita and PS3 versions of Street Fighter X Tekken.
Pac-Man will be featured riding Mokujin, while the Mega Man selected is the "classic" (See also: Terrible) box art character from the original Mega Man game in the US.
"If you're like me, you may be wondering, 'w... why that version of Mega Man?' Well, in the spirit of crossover fun, the dev team wanted both Capcom and Namco's mascots to join the fray in a slightly silly, goofy way," Capcom's community manager Brett Elston wrote on his Capcom-Unity blog.
As for the classic Blue Bomber, Capcom says more is to come for him. "Make no mistake though, classic Blue Bomber Mega Man still has a future, and we have Top Men (not Top Man) on the case." December marks the 25th anniversary for the classic character.
[Update] Capcom has confirmed that all bonus characters--Sony cats Kuro and Toro, Pac-Man, Mega Man, and Cole McGrath from Infamous will be available on both the PS3 and Vita.
